Well I dunno was it really an accident or all of them getting TBI like 110 American troops in Al-Asad air base all the sudden but Iran would not forget or let them get away like this:
Back in January 2007 American raided Iran consulate in the northern city of Irbil and took 5 Iranian diplomats as hostages, Iran did this:
Karbala provincial headquarters raid
“The precision of the attack, the equipment used and the possible use of explosives to destroy the military vehicles in the compound suggests that the attack was well rehearsed prior to execution,” said Lt. Col. Scott Bleichwehl, spokesman for Multi-National Division-Baghdad.
“The attackers went straight to where Americans were located in the provincial government facility, bypassing the Iraqi police in the compound,” said Bleichwehl. “We are looking at all the evidence to determine who or what was responsible for the breakdown in security at the compound and the perpetration of the assault.”
The Karbala raid, as explained by the Iraqi and American officials, began after nightfall at about 6 p.m. on Jan. 20, while American military officers were meeting with their Iraqi counterparts on the main floor of the Provisional Joint Coordination Center in Karbala.
Convoy was waved through
Iraqi officials said the approaching convoy of black GMC Suburbans was waved through an Iraqi checkpoint at the edge of Karbala. The Iraqi soldiers believed it to be American because of the type of vehicles, the distinctive camouflage American uniforms and the fact that they spoke English. One Iraqi official said the leader of the assault team was blond, but no other official confirmed that.
One soldier died in compound
The attackers threw a grenade and opened fire with automatic rifles as they grabbed two soldiers inside the compound. Then the guerrilla assault team jumped on top of an armored U.S. Humvee and captured two more soldiers, the U.S. military officials said.
One U.S. soldier was killed in the melee at the compound, and three were wounded.
The attackers captured four soldiers and fled with them and the computer east toward Mahawil, the U.S. military officials said.
The Iraqi officials said the four were captured alive and shot just before the vehicles were abandoned.
Police who became suspicious when the convoy of attackers and their American captives did not stop at a roadblock chased the vehicles and found the bodies, the gear and the abandoned SUVs.
